Product Warranty  
Advantech warrants to you, the original purchaser, that each of its prod-  
ucts will be free from defects in materials and workmanship for one year  
from the date of purchase.  
This warranty does not apply to any products that have been repaired or  
altered by persons other than repair personnel authorized by Advantech,  
or which have been subject to misuse, abuse, accident or improper instal-  
lation. Advantech assumes no liability under the terms of this warranty as  
a consequence of such events.  
Because of Advantech high quality-control standards and rigorous test-  
ing, most of our customers never need to use our repair service. If an  
Advantech product is defective, it will be repaired or replaced at no  
charge during the warranty period. For out-of-warranty repairs, you will  
be billed according to the cost of replacement materials, service time and  
freight. Please consult your dealer for more details. If you think you have  
a defective product, follow these steps:  
Step 1. Collect all the information about the problem encountered. (For  
example, CPU speed, Advantech products used, other hardware  
and software used, etc.) Note anything abnormal and list any on-  
screen messages you get when the problem occurs.  
Step 2. Call your dealer and describe the problem. Please have your man-  
ual, product, and any helpful information readily available.  
Step 3. If your product is diagnosed as defective, obtain an RMA (return  
merchandize authorization) number from your dealer. This  
allows us to process your return more quickly.  
Step 4. Carefully pack the defective product, a fully completed Repair  
and Replacement Order Card and a photocopy proof of purchase  
date (such as your sales receipt) in a shippable container. A prod-  
uct returned without proof of the purchase date is not eligible for  
warranty service.  
Step 5. Write the RMA number visibly on the outside of the package and  
ship it prepaid to your dealer.

Safety Precaution - Static Electricity  
Follow these simple precautions to protect yourself from harm and the  
products from damage. To avoid electrical shock, always disconnect the  
power from your PC chassis before you work on it. Don't touch any com-  
ponents on the CPU card or other cards while the PC is on. Disconnect  
power before making any configuration changes. The sudden rush of  
power as you connect a jumper or install a card may damage sensitive  
electronic components.

1.3 Safety Precautions  
The following sections tell how to make each connection. In most cases,  
you will simply need to connect a standard cable.  
Warning! Always disconnect the power cord from your  
chassis whenever you are working on it. Do not  
connect while the power is on. A sudden rush of  
power can damage sensitive electronic compo-  
nents. Only experienced electronics personnel  
should open the chassis.  
Caution!  
Always ground yourself to remove any static  
electric charge before touching UNO-2173A/AF.  
Modern electronic devices are very sensitive to  
static electric charges. Use a grounding wrist  
strap at all times. Place all electronic compo-  
nents on a static-dissipative surface or in a static-  
shielded bag.

Chapter 2 Hardware Functionality  
2.1 Introduction  
The following two figures show the connectors on UNO-2173A/AF. The  
following sections give you detailed information about function of each  
peripheral.  
Figure 2.1: Front panel of UNO-2173A/AF  
Figure 2.2: Rear panel of UNO-2173AF  
2.2 RS-232 Interface (COM1~COM2)  
The UNO-2173A/AF offers two standard RS-232 serial communication  
interface ports: COM1 and COM2. Please refer to A.3 for their pin  
assignments.  
IRQ and Address Setting  
The IRQ and I/O address range of COM1 and COM2 are listed below:  
COM1: 3F8H, IRQ4  
COM2: 2F8H, IRQ3

2.3 RS-422/485 Interface (UNO-2173AF)  
The UNO-2173AF offers one RS-422/485 serial communication interface  
ports: COM3. Please refer to Appendix A.4 for their pin assignments. The  
default setting of COM3 is RS-422.  
2.3.1 RS-422/485 Selection  
The mode of UNO-2173AF COM3 can be selected in the BIOS. Please  
enter the BIOS setting screen and select the "Integrated Peripherals", then  
the follow screen would be shown. In the screen you can configure the  
resource and the mode.  
2.3.2 Automatic Data Flow Control Function for RS-485  
In RS-485 mode, UNO-2173AF automatically detects the direction of  
incoming data and switches its transmission direction accordingly. So no  
handshaking signal (e.g. RTS signal) is necessary. This lets you conve-  
niently build an RS-485 network with just two wires. More importantly,  
application software previously written for half duplex RS-232 environ-  
ments can be maintained without modification.
